lima: add natively supported vertex buffer formats 

Add natively supported vertex buffer formats. If formats are not listed
here as natively supported, mesa triggers a buffer format translation
routine per draw call which can be expensive.
This helps improve performance in some applications.
The 32-bit integer formats were found by trial and error with a script
and checked in particular with piglit test gl-2.0-vertexattribpointer.
